I have heard of a possible Pixie Hollow mobile app. Some people on the forums emailed the idea to Disney, and they said they would consider it. If I find any other news about Pixie Hollow possibly reopening or Pixie Hollow remakes, it will go here.
There is a site called FairyABC that is in progress. It has taken a long time, so hopefully is will be close to the real Pixie Hollow.
